Subject: [PATCH] target/i386: Add new CPU model SierraForest
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
commit 6e82d3b6220777667968a04c87e1667f164ebe88 upstream.
According to table 1-2 in Intel Architecture Instruction Set Extensions and
Future Features (rev 051) [1], SierraForest has the following new features
which have already been virtualized:
- CMPCCXADD CPUID.(EAX=7,ECX=1):EAX[bit 7]
- AVX-IFMA CPUID.(EAX=7,ECX=1):EAX[bit 23]
- AVX-VNNI-INT8 CPUID.(EAX=7,ECX=1):EDX[bit 4]
- AVX-NE-CONVERT CPUID.(EAX=7,ECX=1):EDX[bit 5]
Add above features to new CPU model SierraForest. Comparing with GraniteRapids
CPU model, SierraForest bare-metal removes the following features:
- HLE CPUID.(EAX=7,ECX=0):EBX[bit 4]
- RTM CPUID.(EAX=7,ECX=0):EBX[bit 11]
- AVX512F CPUID.(EAX=7,ECX=0):EBX[bit 16]
- AVX512DQ CPUID.(EAX=7,ECX=0):EBX[bit 17]
- AVX512_IFMA CPUID.(EAX=7,ECX=0):EBX[bit 21]
- AVX512CD CPUID.(EAX=7,ECX=0):EBX[bit 28]
- AVX512BW CPUID.(EAX=7,ECX=0):EBX[bit 30]
- AVX512VL CPUID.(EAX=7,ECX=0):EBX[bit 31]
- AVX512_VBMI CPUID.(EAX=7,ECX=0):ECX[bit 1]
- AVX512_VBMI2 CPUID.(EAX=7,ECX=0):ECX[bit 6]
- AVX512_VNNI CPUID.(EAX=7,ECX=0):ECX[bit 11]
- AVX512_BITALG CPUID.(EAX=7,ECX=0):ECX[bit 12]
- AVX512_VPOPCNTDQ CPUID.(EAX=7,ECX=0):ECX[bit 14]
- LA57 CPUID.(EAX=7,ECX=0):ECX[bit 16]
- TSXLDTRK CPUID.(EAX=7,ECX=0):EDX[bit 16]
- AMX-BF16 CPUID.(EAX=7,ECX=0):EDX[bit 22]
- AVX512_FP16 CPUID.(EAX=7,ECX=0):EDX[bit 23]
- AMX-TILE CPUID.(EAX=7,ECX=0):EDX[bit 24]
- AMX-INT8 CPUID.(EAX=7,ECX=0):EDX[bit 25]
- AVX512_BF16 CPUID.(EAX=7,ECX=1):EAX[bit 5]
- fast zero-length MOVSB CPUID.(EAX=7,ECX=1):EAX[bit 10]
- fast short CMPSB, SCASB CPUID.(EAX=7,ECX=1):EAX[bit 12]
- AMX-FP16 CPUID.(EAX=7,ECX=1):EAX[bit 21]
- PREFETCHI CPUID.(EAX=7,ECX=1):EDX[bit 14]
- XFD CPUID.(EAX=0xD,ECX=1):EAX[bit 4]
- EPT_PAGE_WALK_LENGTH_5 VMX_EPT_VPID_CAP(0x48c)[bit 7]
Add all features of GraniteRapids CPU model except above features to
SierraForest CPU model.
SierraForest doesn’t support TSX and RTM but supports TAA_NO. When RTM is
not enabled in host, KVM will not report TAA_NO. So, just don't include
TAA_NO in SierraForest CPU model.
